无线3G交通监控与事故防范系统的方案设计与实现

DESIGN AND REALISATION OF TRAFFIC MONITORING AND ACCIDENT PREVENTION SYSTEM BASED ON WIRELESS 3G

针对当前交通监控系统的诸多不足,提出一种基于无线3G的交通监控系统的方案。该系统前端监控节点可对交通视频图像以及天气状况等多种信息进行采集,并且依据相关信息分析路况,对可能出现的事故进行防范预警。节点通过3G网络传输数据,可以根据需要灵活移动。后端由多个不同功能的服务器组成,将前端的视频信息重新封包,使用RTSP协议进行传输,气象等相关数据储存在数据库中。后端结合视频图像以及气象路况信息对事故隐患进行二次判断。实验表明,该系统能够准确获取信息,达到设计要求。

As to the shortcomings of current traffic monitoring system,we present in this article a traffic monitoring system scheme which is based on wireless 3G. In the system the monitoring nodes in front end can capture multiple information of transportation video images and weather conditions,and analyse the traffic conditions according to correlated information,and carry out the prevention and early alarm on possible accidents. The nodes transmit the data through 3G networks and can move flexibly according to the demand. The rear end consists of several servers with different functions. It re-capsulates the video information from the front ends and transmits them upon the RTSP protocol,the related meteorological data or so are stored in database. The rear end makes secondary estimation on the pitfalls of accidents in combination with the information of video images and weather and traffic conditions. Experiment shows that the system can capture the information accurately and meets the design requirement.
